[mpl] Metafunction to extract type
Does MPL already have a metafunction which takes a type, which is a nullary metafunction, and returns the nullary metafunction's nested type ? As in: template < class T > struct get_type : T { };

I, of course, read too fast. Discard previous answer. Now question, why do you need this apparently useless feature ? can't you pass nullary metafunction along ?

You are correct. There is no need for it. I had not thought about what I was trying to do in my particular instance enough.
